Mouse problems

[Jackal]

I apologize if this topic has been brought up before, but I can't find the exact problem I have been having in these threads. I am having problems with controlling my mouse on the screen. I cannot even click on the start menu to create my name when I go to play. I downloaded the game a few years ago off steam, and I played it before successfully on my old laptop, but I never got around to beating it. I'm playing it now on windows 10 with my asus, and am unable to do anything with the game. please help me as soon as possible, would love to get this game started again.
